Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

“ipv4_connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“”,“actual_external_ipv6”:“null”,“router_external_ip”:“null”},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}

As a first step, your probably just have to enable UPnP on the router or, alternatively, set up a manual port forwarding rule. See here, from the troubleshooting help page:
